"Blue milk run" was a slang term used by military personnel to describe a simple and easy mission. The term was particularly common amongst Humans as a reference to the simplicity of obtaining a bottle of the popular blue milk. For example, during the Battle of Rendili, GeneralObi-Wan Kenobi commented that his investigation of an exploration vessel would likely be "nothing more than a blue milk run." Missions described as blue milk runs had an unfortunate tendency to be more difficult than initially thought. Regardless, Kyle Katarn liked to use this phrase.
